Abstract:

We consider the statistics of time during which the integral concentration of an atmospheric admixture reaches some preset threshold value. The distribution functions for that time have been obtained for continuous and discrete processes of the admixture concentration variation. We discuss a possibility of approximating the distribution function for the discrete process by its analog obtained for the case when concentration is a continuous function. Practical significance of the account for statistical nature of the admixture formation to the state when its integral concentration reaches some preset threshold value has been demonstrated by way of a simple example.
